Problem while running Azure Function

Question

_{Tuesday, December 17, 2019 8:23 AM}

Hi,

Each time I'm running the Azure Function, I'm getting:

A host error has occurred
[17/12/2019 08:19:00] Microsoft.Azure.WebJobs.Extensions.Storage: Could not load type 'Microsoft.Azure.WebJobs.Host.Scale.IScaleMonitorProvider' from assembly 'Microsoft.Azure.WebJobs.Host, Version=3.0.13.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Those are the version I'm using:

Azure Functions Core Tools (2.7.1633 Commit hash: 45c7d86a3bbc9ed0a80a8f4199aa7ea80ccfb24e)
Function Runtime Version: 2.0.12673.0
Microsoft.Azure.WebJobs.Host, Version=3.0.13.0
Microsoft.NET.Sdk.Functions (3.0.2)
Microsoft.Azure.WebJobs (3.0.14)

Any ideas? :(

Best regards,

Michal

When host or CLI tools is out of date. Please make sure you’re running the latest tools.

The latest version of the runtime (2.0.12858) should be loading 3.0.14.

If you are running from Visual Studio you should see a similar message printed at the top

Azure Functions Core Tools (2.7.1846 Commit hash: 458c671341fda1c52bd46e1aa8943cb26e467830) Function Runtime Version: 2.0.12858.0

or

Generally we got this when we are using Azure Storage based functionality (blob/queue/tables trigger/input/output) and have some issue in Microsoft.Azure.WebJobs.Extensions.Storage extension.

Could you try get the Microsoft.Azure.WebJobs.Extensions.Storage Nuget  Package.

For non-C# apps, running func extensions install  should pull in the right storage extension.

Do let me know how it goes.

FWIW

When running from Visual Studio it was still getting an older version. I cleaned up all the folders under 'C:\Users\username>\AppData\Local\AzureFunctionsTools\Releases\ and started again and it worked. Got the path from the console that fires up when running Azure functions
